Flour as needed to thicken toast garlic cloves (peeled and washed) in a 350 degree oven until smooshy and brown, chop garlic with a fork, add everything except half and half. cook over low heat until all cheese has melted but not until it starts getting greasy. add half and half, cook until thick (add flour slowly if needed, because this sauce thickens itself very well!!!) chill overnight, reheat and serve
